The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for Kennebunk Beach over the next couple of weeks. I gotta be straight with you, it's looking pretty grim for a paddle. We've got a long, dry stretch of small, weak surf ahead.
The good news? The water is a touch warmer than normal for this time of year, coming in at 66°F, which is nice. But that's about the only highlight for a while.
We kick off this Sunday morning, the 6th of September, with the best we're gonna see for a while. It's not saying much. Kennebunk Beach is a sheltered spot, so it needs a decent push from the ENE to work. We've got a 4ft swell coming from the NE, but with a short period of just 6 seconds, it's lacking any real punch. The combined wave energy is moderate at best (242). The wind is a light cross-offshore from the NNW, so the surface will be clean. But honestly, this is a weak, short-period windswell, and the conditions are very ordinary. It's surfable, but it's not going to get the heart racing. By Sunday afternoon, the swell drops off a cliff to 2ft and the score is a zero.
From there, it’s a wasteland. Monday the 7th through to the end of the first week is nothing but flat, tiny waves – 1.0ft or less. There's a day or two of glassy conditions, but with no swell to ride, it's a lake. That's a solid 4 to 5-day gap with absolutely nothing worth paddling out for.
Heading into the second week, things don't get much better. We see a tiny bump of 3ft on Monday the 14th, but it's a choppy, onshore mess. Then on Wednesday the 16th, we get a bit more energy. The swell jumps to 5ft from the ENE with a short 6-second period. The combined energy is a moderate 181, and we have a fresh offshore wind from the NNE. It'll be clean, but that short period and the fact that it's a beach break setup means it's going to be a bit of a washing machine. It's also raining with moderate rain, which is miserable. Not a standout, just the most notable bump in a very flat period. It could be more interesting for kite surfing than paddling, to be honest.
The following Thursday and Friday (17th & 18th) see the swell drop back to under 3ft. It's small, weak, and unremarkable.
So, looking at the whole 16-day picture, there's simply no true standout session. The best of a bad bunch is that Sunday morning, September 6th, but even that is just "surfable." The rest is a long, flat run that's pretty normal for this area when the conditions don't align. I'd keep an eye on the charts, but don't hold your breath.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
